1/4" End Mill Single End Ball. Extra-Extra Long Lengths. Shank OD 1/4" Flute Length 3" OAL 6" - 2 Flutes - AlTiN Coated

1/4" cutting diameter, 2 flutes, single end, ball nose, extra-extra long length, AlTiN coated.

Ground from solid carbide. This tool cuts 1/4" diameter, runs a 1/4" shank, has 3" of flute and measures 6" overall.

The ball nose leaves a radiused bottom, which is what you want for 3D contours, fillets and mould surfaces rather than flat floors.

Built for the deepest reaches; support the part and take lighter radial cuts, because deflection grows fast with length.

AlTiN is built for heat: stainless, tool steels and high-temperature alloys, especially with little or no coolant.
